Pepperl+Fuchs has introduced a Bebco EPS® purge and pressurization system designed specifically for use with large enclosures in Zone 1 hazardous areas. The 6100 series purge and pressurization system can purge an enclosure over 450 cubic feet (12.2 cubic meters), making it the largest purging system available from Pepperl+Fuchs. The 6100 series system is perfect for applications in the chemical/petrochemical and oil and gas industries.

The 6100 series is a fully automatic system that does not require an operator to initiate purging or pressurization. It offers optional temperature sensors that can be mounted around the enclosure for alarm notification or cooling. Additionally, there is automatic pressure compensation for excess leakage from the enclosure.

The 6100 system consists of a control unit, vent, low pressure sensor, and optional temperature sensors. The control unit allows users to configure the system for size of motor, temperature switch points, pressure switch points for leakage compensation and shutoff pressure, extra output for control or alarm, two selectable intrinsically safe inputs for various actions, and up to three temperature sensor inputs that can monitor various points within the enclosure. The intrinsically safe user-interface can also be mounted in a separate enclosure near an operator for quick access and easy system monitoring.

The intrinsically safe pressure sensor provides an accurate enclosure pressure reading for safe operation within the hazardous area. The pressure sensor—which can measure internal pressure from 0 to 25 mbar—can be remotely located at the enclosure's low pressure section for correct, safe pressure readings.

The EPV-6100 vent can be ordered to detect various flows for purging and then feedback the signal to the 6100 series control unit to start the purge timer. There are five flow rates to choose from (14,000 l/min maximum) to meet any application requirement in large enclosures and some large motors.

Additional features of the 6100 series include system bypass, manual enclosure power on/off, temperature activation of purging for cooling purposes, and delay of power shutdown upon loss of pressure for pressure correction for shutdown procedures.

The 6100 Series Phase I is designed for large enclosures to keep the pressure low during purging. Phase II will be designed for large motors where the purge and pressurization pressure has to be higher to compensate for the rotating machinery inside. 

 

  • Certified for ATEX and IECEx Zone 1
  • Fully automatic
  • Maximum flow rate of 14,000 l/min
  • Intrinsically safe user-interface for system programming and monitoring
  • Control unit monitors system operation and controls enclosure power
  • Auxiliary contact outputs for alarm or control
  • Multiple temperature inputs for monitoring and control
  • Automatic pressure compensation for excess leakage from enclosure
  • Keeps enclosure pressure low during purging

Rittal is replacing its previous KS series with the new fibreglass enclosures AX and so completely redefining fibreglass enclosure technology. The development is based on Rittal’s technology for sheet steel and stainless-steel enclosures, which can be used to greatly simplify and speed up manufacturing processes in panel building and switchgear manufacturing. Now, for the first time, fibreglass enclosures also feature this system technology. This is a win-win situation for plant constructors:

Selecting a panel meter for a particular application can be a daunting task, given the wide variety of products that are available today. There are many factors to consider when making a decision. Let’s look at a few of the major items.

Function

Panel meters can be categorized by type, size, style or other criteria. One way to begin the selection process is to look at the meter’s function – what measurement is this meter making? Some common functions are ammeter, voltmeter, frequency meter, power meter, energy meter, counter, timer, temperature meter, process meter, and controller.
